TiO(2)/H-ZSM-5 catalysts were prepared by impregnation with different amount of TiO(2) loading and calcination at various temperatures. The catalysts were characterized by X-ray diffraction (XRD), ultraviolet and visible spectroscopy (UV-vis) and BET specific surface area. It was demonstrated that the anatase TiO(2) retained stable on H-ZSM-5 after heat treatment even at 700 degrees C. The activities of samples were investigated under the various conditions of UV, ozone and UV-ozone, respectively by the comparison of acetaldehyde degradation. It was found that the photocatalysis combined with ozonation promoted the acetaldehyde degradation. TiO(2)/H-ZSM-5 catalysts were superior to simple TiO(2) and H-ZSM-5 with respect to the ozone-assisted photocatalytic oxidation of gaseous acetaldehyde, and the activity of the catalyst TiO(2)/H-ZSM-5 (TiO(2):H-ZSM-5=2:10) is the highest one among all those prepared samples. The improvement was attributed to the synergetic effect among adsorption, ozonation and catalytic reaction.
